roads and for' other Purposes, which is de-f scribed as follows, reference being had to the annexed drawings of the same, making part of this specification.

Figure 1, is a front elevation ofthe .ma

chinery. Fig. 2,'is a side elevation. Fing. 3; is a top view Of the cogged rollers. Fig. 4

is a front elevation of the hammer. Fig. 5,

is a top View of ditto. Fig. 6 is a top view of the anvil.

Similar letters in the several gures refer to corresponding parts.

A is the frame of the machine.v

B is the anvil.

C is the hammer.

D is the handle of the hammer.

E E are the friction rollers for raising the hammer.

F are cogs on the periphery of the rollers to engage the one withl the other when the rollers are to be revolved together to raise the hammer.

E is the driving axle of the back or driving roller.

VE2 is the vibrating axle of the front friction roller. Y

F are gudgeons of the front roller one of which turns in an upright plate Gr secured to the frame and the other turns in the upper ends of a vibrating lever H for throwing the cogs of the front roller in and out of gear with the cogs of the back roller. l I is the fulcrum of said lever.

K is a pulley on the aXle of the back roller for the band leading tothe propelling power.

L L are two parallel hanging guides for guiding the hammer in its ascent and descent having their inner edges made of a V` to correspond with a V shaped groove made in the edges of the hammer. M is a rock shaftl into which the upper ends of these guides are inserted the lower ends being detached.

M N are the gudgeons of the rock shaft turning in the parallel timbers o o of the frame.

P is a lever for moving the lower ends of the hanging levers in the arc of a circle. Q, is the fulcrum of said levers.

R is a jointed connecting rod and segment bale V for connecting the swing `guides to ..-thelever, said lever serving -to move *theiry lowerfends back 'and forth in bringing the hammer perpendicularly 'over the bar of ironitobe' straightened. l

bent linbringing it to a straightline.

W, W, are antifriction rollers which are to ectionsl on Vthe upper be raised slightly above the bevelofthe an-A vil on rolling'ona bar to be straightened and to be depressed below it during the'opera# tion of hammering it so as to bringy thebar l down upon the bearing points of the anvil.k

X is a combination of levers for raising and depressing the rollers attachedto the anvil. Y

The width ofk the channels around the coggedrollers formed bythe two circles ofv cogs is a little greater than the width of the handle of the hammer.

The frame may be of any required form, size, and strength adapted to the machinery Vto be placed therein-'either connected with the timbers of the building in a hanging position or resting upon posts on a permanent bed, or platform, or in any convenient way.

Operation: The rear shaft Ey and cog Wheel F being put in motion by the application of any convenient power tothe Vdriving pulley K on said shaft lay hold of the lever H and move the roller E or the vibrating shaft E2 against the handle D ofthe hammer. The teeth of theV cog wheels of `both rollers beingin gear will cause the hammer rollers to descend belowthe level of the top Raise the rollers W, byv

of the anvil which Will bring the bar of iron down upon the anvil. v

Lay hold of the lever P and move it to the right or left, causing the vibrating guide arms to move also to the right or left'until the hammer is perpendioularly above the bar of iron to be straightened, then reversethe movement of thellever H attached to the vibrating shaft. This Will liberate the hammer handle and cause the hammer to descend upon the bar of iron With-suficient force to straighten it. But should one blow not be suflicient the operation must be repeated as often as is necessary toV effect the desired object. The force of the first and each'succeeding blor Will be determined by the height to which the hammer is raised and indicated by the perforated gageS.

I do not claim the invention of a gravit-ating Weight for bending and straightening bars of iron7 but,

What I do claim as my invention and desire to secure by; Letters Patent, is-

l.V The manner of directing the Weight in its descent so as torstrike the bar of iron in the point desired by the employment of the hanging arms L in .combination With the -rock shaft M into which they are inserted JoHN ANDERSON.
